Answer: 2/9 divided by 7/9 = 2/7
Step-by-step explanation:
1. Write out the problem on a piece of paper.
2. Change the second fraction, which is 7/9, into a reciprocal fraction (means flipping the 7 and 9 around). Now, our equation has the fraction 9/7 in it.
3. Change the division symbol to a multiplication symbol. Your equation should be 2/9 x 9/7.
4. Solve the equation. You should get the answer of 18/63 without simplification.
5. Simplify. 18/63 = 2/7
Conclusion: 2/7 is the correct answer.
If you factor the denominator of the left multiplicand...
[(a-4)(a+3)]/[a(a-4)] you can see that the (a-4)s cancel out leaving:
(a+3)/a
now you have
(a+3)/a * 2a^3/((a+3)(a-1)) so the (a+3)s cancel out leaving:
1/a * 2a^3/(a-1) which is:
2a^3/(a(a-1)) so now a^1 cancel leaving
2a^2/(a-1)
Your points: (5,2)
Your inequality: x - y < 0
Plug 5 in for x and y in for 2
5 - 2 < 0.
Simplify the left side
3 < 0.
3 is not less than 0
(5,2) is not a solution of x - y < 0
Answer:
x = 9
Step-by-step explanation:
-4(6x+3)=-12(x+10)
-24x-12=-12x-120
+12 +12
-12x=-12x-108
/-12 /-12 / -12
x=9
Answer x=9
